Dark green leafy vegetables Many dark green leafy vegetables have relatively high calcium concentrations. The calcium in spinach is however, somewhat poorly absorbed, probably because of the high concentration of oxalate. The study revealed that kale, a low-oxalate vegetable, is a good source of bioavailable calcium. Kale is a member of the same family that includes broccoli, turnip greens, collard greens and mustard greens. These low-oxalate, calcium-rich vegetables are therefore also likely to be better sources of available calcium
